ILE ANAGEMENT
The following three situations are concerned with the main/backup attributes:
When saving the current configuration, you can specify the file to be a main or
■
backup or normal configuration file.
When removing a configuration file from a device, you can specify to remove
■
the main or backup configuration file. Or, if it is a file having both main and
backup attribute, you can specify to erase the main or backup attribute of the
file.
When setting the configuration file for next startup, you can specify to use the
■
main or backup configuration file.
Startup with the configuration file
When booting, the system chooses the .cfg configuration files following the rules
below:
1 If the main configuration file exists, the switch initializes with this configuration.
2 If the main configuration file does not exist but the backup configuration file
exists, the switch initializes with the backup configuration.
3 If neither the main nor the backup configuration file exists, switch initializes with
the default configuration file which ends in a .def file extension (e.g.,
3comoscfg-26Port.def). This has factory-loaded default settings recommended by
3Com. There is a specific .def file for each switch type.
If the default (.def) configuration file does not exist, the switch will come up with
the switch internal defaults.

Specifying a configuration file for next startup
You can modify the configuration on your device at the command line interface
(CLI). To use the modified configuration for your subsequent startups, you must
save it (using the save command) as a configuration file.

Modes in saving the configuration
Fast saving mode. This is the mode when you use the save command without
■
the safely keyword. The mode saves the file quicker but is likely to lose the
original configuration file if the device reboots or the power fails during the
process.
Safe mode. This is the mode when you use the save command with the safely
■
keyword. The mode saves the file slower but can retain the original
